For the second location of popular south side burger bar Oscar’s Pub & Grill, the owners are doing something different.

The menu wasn’t exactly like the original as Oscar’s Winner’s Circle debuted Monday at 3800 W. Burnham Ave., complete with 40 taps for craft beers and mariachi music for the opening.

Oscar Castañeda, who operates the taverns with his wife, Elisabeth Stoeger, said the menu on Burnham still features burgers, but toppings differ from the original menu. They’ll incorporate Mexican flavors, as in the chicharrón burger, topped with crisp fried pork rinds, and a burger alhambra with melted Chihuahua cheese and fresh avocado slices.

The special on Tuesdays will be a Mexican plate, such as enchiladas, and fish fry will be served on Fridays, with this location serving potato pancakes.

Oscar’s Winner’s Circle has a children’s menu, with items such as grilled cheese, quesadilla and chicken tenders.

Prices are in the same range at the new location, with most of the half-pound Angus burgers around $6 to $7, which includes house-cut fries.

A patio will be installed on the west side of the building in the coming months, and Castañeda would like to serve his favorite, tacos al pastor, outdoors in summer. The meat would be cut from a trompo roasted on a vertical rotisserie and, if everything goes as planned, served on house-made tortillas.

Oscar’s has a full bar, and the beers mainly will be on draft; a few beers such as Miller and Miller Lite will be served in bottles. Beers on tap will include Milwaukee and state brews from Enlightened, Eagle Park, Westallion, New Glarus and others, as well as beer from neighboring states, such as Pipeworks in Chicago.

The tavern at 38th and Burnham for years was known as the Winner’s Circle; Castañeda kept the name but remodeled the interior. It has seats for 54 customers.

The kitchen will be open 11 a.m. to 11 p.m. Monday to Friday and 9 a.m. to 11 p.m. Saturday and Sunday. Oscar’s will serve breakfast on the weekends, but burgers will be available in the mornings, too.
